Step 4: Sealing the computer
1. It is heat resistant and won't melt if put on a heatsink.
2. It is more water resistance.
3. It is more durable.
4. Drys slower, allowing more time to fix mistakes and to put on cover.
5. It is flexable.
Flexability is key when using around buttons and switches.
Start with the processor. This is the MOST important part of the computer and also the most expensive to replace. Take all heatsinks off and make a sqare around the processor with the silicon. Don't put any silicon on the processor. Just around it. If the heatsink is connected to any other chips or circuitry then put a square around that too. It is probally pretty important. Stick the heatsink back on and allow to dry. If there are any screw holes in the heat sink, replace the screws and fill in with silicon.
Next, take a paper towel and squirt some silicon on it (can't do this step with hot glue). Rub the silicon all over the motherboard. This will protect it a little if any water does manage to find its way in.
Now, start reasembling the laptop. Start with the parts in the middle and work your way out. Make sure you seal the piece to the board and put some silicon all around the top of the daughterboard or device. Keep working quickly but carfully as silicon tends to dry.
If your computer has speakers then we need to fix those too. The cone in speakers is sometimes made of paper and will get soggy and will leak water. Take some silicon and put it on your finger (a glove might help). Spread a thin but full coat on the cone of the speaker. This shouldn't effect the speaker.
Make sure the whole circuitry and devices (esp. the processor and battery) are completly sealed off. We don't want any leaks.
